it sounds like he wants a ram not a chevy i would go with the personally but that is in part due to the lack of the push button tranny which just pisses me off i would not get the high output cummins but get the aisin if you can spec it out should be able to aisin is a better trans then the other ram options but the high output is a waste i tow k regularly with a stock which a boatload less torque then even the detuned cummins with the manual on the new rams it pulls fine for me
